Henna and Ringworm?

I was just curious after reading some things on the Hennapage I found that henna has been used to treat ringworm. Does it work? I've used henna once before just for simple designs but never heard of it being used as treatment. I've had ringworm before from kittens I've fostered and currently have more ringworm kittens and waiting to see if I will get it. Has anyone tried this? Would it be safe to try?

For the last two summers, I've used henna to successfuly rid my dog of ringworm. It does a fantastic job! I caught it too, and henna knocked it off me. My dog's fur returned, and there's no trace of what were ugly itchy patches.
